Hi,
I'm going through the tutorial on Mate and having some issues with
send_lqi
(or maybe not) on T-Sky/telosb. If I am reading the documentation
right,
send_lqi acts as a drop-in for send, and thus the packets forwarded
via
send_lqi would be output at the root node as the data. I have run
the mica
pc sim, and see the traffic just fine using TOSSIM and the
VMBufferReader.
Now I just get
Received UART message containing type NONE, ignoring.
Received UART message containing type NONE, ignoring.
Received UART message containing type NONE, ignoring.
Anytime a message comes over the UART. I have gotten directly
connected
nodes to send other UART data and have it recognized.

Is a sample from the data via net.tinyos.tools.Listen
It's configured at 57600 for the data rate.
Also, when I am compiling BombillaTelosB, I see a cannot find
MateBufferMsg
AM type in the log.
Because it's using multihop routing, it will me AM_MATEROUTEMSG
(0x1b): you can see it above in the log, after the address. The
packet format is:
802.15.4 header
Multihop Header
I think the problem is that tos/lib/MultihopLQI changed the packet
format, and I didn't update Mate' to consider this fact. E.g., if you
look at
tos/lib/MultihopLQI/Multihop.h
and
tos/lib/VM/types/mhop.h
The structures are different. If you change tos/lib/VM/types/mhop.h
to be the kind of wasteful
typedef struct MultihopMsg {
uint16_t sourceaddr;
uint16_t originaddr;
int16_t seqno;
int16_t originseqno;
uint16_t hopcount;
uint8_t data[(TOSH_DATA_LENGTH - 10)];
} TOS_MHopMsg;
(wasteful in that it has 16-bit sequence numbers and hopcounts) does
it work?
